One of the more prophetic books EVER written was The Economic Consequences of the Peace, by John Maynard Keynes, published in 1919, which pretty much foretold World War II, based upon the very unfairness of the Treaty of Versailles that you are commenting on here.

P.S. I have heard some historians refer to the Napoleonic Wars as World War Zero. That truly was a globalized conflict.

Not for Russia, certainly. Over there, there was WWI, which killed 2.2 million Russian troops and another 2 million Russian civilians. Then, in 1917, the Bolshevik Revolution, and resulting Civil War, which killed up to 10 million by some estimates, both civilians and combatants, and drove over 2 million refugees out of the country. Then, after the Commies won and fully took over, millions and millions more dead in all their various Terrors and Purges, under Lenin and Stalin. And then - WWII for good measure.

Yeah, for that part of the world, all those decades just fucking sucked, period...

I agree with the belief that the WWII was a direct result of the first and should be conflated historically. Although I do not have the time to explain my reasons now ( I have an appointment), it is becoming the accepted view among historians that the two wars are the same conflict with a brief hiatus.

I don't know if it was "Unfair" to Germany it was very punitive against Germany, which created economic hell for the next 2 decades, which resulted in the rise of Socialism in Germany.

Well, an 'armistice' was turned into a defeat at Versailles, and Nazism bears no relationship to 'socialism' (how many times does this fact have to be explained?), and it comes under the umbrella of 'Totalitarianism'. The term 'Socialism' was a leftover from the original party formed by trade unions which was later hijacked by Hitler and altered to suit his own ends.
